BOILER-FLUE BEADER.

SPECIFICATION forming part of Letters Patent No. 439,496, dated October 28, 1890.

Application filed August 18, 1890. Serial No. 362,289. (No model.)

To all whom t may concern.'

Be it known that I, BENJAMIN BLANTON FARRIS, of Rocky Ford, in the county of Screven and State of Georgia, have invented a new and Improved Boiler-Flue Beader, of which the following is a full, clear, and exact description.

The invention relates to boiler-Hue beaders, such as shown and described in the application for Letters Patent, Serial No. 348,485, by me April 18,1890, and allowed July 1,

The object of the present invention is to provide a new and improved boilerflue header, which is simple and durable in construction and forms a bead on the inner as well as on the outer face of the head-plate of the boiler, so as to prevent all leakage.

The invention consists of a head carrying a series of interior beading-rollers, a tapering spindle adapted to pass through the said head to drive the said rollers outward, and a block mounted to turn on the said head and carrying beading-rollers adapted to engage the pro jecting end of the tube or i'iue.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specication, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied and with parts in section. Fig. 2 is a transverse section of the same on the line @c a: of Fig. 1. Fig. 3 is a plan view of the improvement with parts in section and as arranged for cutting oii surplus'material from the projecting end of the tube or flue. Fig. 4 is an end view of the same, and Fig. 5 is a cross-section of the cutter.

The improved boiler-flue header A is provided With a hollow stem B, on one end of which is formed a head C, carrying in its rim a series of beading-rollers D, adapted to engage the inside of the flue or tube E, held in the head F of the boiler. In order to hold the series of rollers D in place, the said head C is provided with suitable recesses for the said rollers, as is plainly illustrated in Fig. 2, and

on the end of the head is screwed a cap C', abutting against the inner faces or ends of the rollers. Each ot the rollers D is provided on its rim with a semicircular bead D', adapted to form a bead E on the tube oriiue E at the inner face of the l1ead-plate F, as is plainly shown in Fig. 1

In order to drive the heading-rollersDoutward to form the said bead E', a tapering spindle G is provided, which passes through the stem B and the head C to force the said rollers outward. On the outer end of the tapering spindle G is arranged a handle H for conveniently turning the spindle G in order to move the beading-rollers D outward, at the same time rotating the same.

On the stem B is mounted to turn loosely a block I, carrying a number of oppositelyarranged pins or studs J, on which are mounted to turn beading-rollers K, held in place by nuts L, screwing on the ou ter threaded ends of the said pins or studs J. The pins or studs J stand radially to the stem B, so that the grooved beading-rollers K engage the projecting end of the iue or tubeE when the block I is rotated. In order to do this the said block I is provided with a polygonal oiset l', adapted to be engaged by a wrench or other suitable instrumentfor conveniently turning the block I.

In order to hold the beading-rollers K in contact with the outer end of thetube or flue E, a nut N screws on the threaded outer end B of of the stem B and against the polyognal offset I ofthe block l. 1u case the projecting end of the tube or flue E is longer than is necessary to form a bead on the outer end, part of this projecting end of the tube has to be cut olf, and for this purpose one of the beading-rollers K is taken o the pin or stud J, andacut ter O is placed on the said stud, as is plainly shown in Figs. 3 and 4. This cutterO is provided with a cutting-edge O', adapted to out the end of the tube or flue, and the said cutter is also provided with a dowel-pin O2, adapted to engage the corresponding recess in the block l, so that the cutter O is prevented from turning on its stud when used for cutting off the end of the tube or iiue.

The operation is as follows: The head C is inserted into the tube or fiue E, so that the IOO annular bead D of each of the beading-roll-v ers D is in the rear of the inner face of the head-plate F. The operator then passes the spindle Gthrough the stem B and the head C, and rotates the said spindle in order to drive the beading-rollers D outward, at the same time rotating the same, so as to form the bead E 0n the inner face of the headplate F. The operator then places the block I on the stem B, so that the rollers K engage the outer end of the tube 0r flue, and then the operator turns the block I, so that the beadinguollers K form the usual bead on the end of the tube or fiue on the front face of the head-plate F. (See Fig. l.) It will be seen that by thus forming the bead on the inner as well as the outer face of the headplate on each tube or flue all leakage is prevented andthe tubes or iiues are securely held in the head-plate F.

It is understood that after the interior bead E is formed the spindle G is left in position, so that the beading-rollers D hold the head C with the stem Bin place to permit the block I to be freely rotated on the said stem for the purpose of beading the outer end of the tube or flue E.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. A boiler-flue beader comprising a head carrying a series of interior beading-rollers,

v a tapering spindle adapted to pass through the said head to drive the said rollers out ward and rotate the same,and a block mounted to turn on the said head and carrying beading-rollers adapted to engage the projecting end of the tube or Hue, substantially as shown and described.

2. In a boiler-flue beader, the combination, with a hollow stem and a head formed thereon, of a series of beading-rollers, each having an annular bead on its rim, the said beadingrollers being held in the said head, and a tapering spindle adapted to pass through the said stem and head to drive the said rollers outward and to rotate the same, substantially as shown and described.

3. In a boiler-flue beader, the combination, with a stem and a head formed thereon, of beading-rollers held in the said head and each provided with an annular semicircular bead, a block mounted to turn on the said stem and provided with radially-arranged pins or studs, and beading-rollers mounted to turn on the said pins or studs, substantially as shown and described.

et. In a boiler-flue beader, the combination, with a stem and a head formed thereon, of beading-rollers held in the said head and each provided With an annular semicircular bead, a block mounted to turn on the said stem and provided with radially-arranged pins or studs, beading-rollers mounted to turn on the said pins or studs, and means, substantially as described, for screwing up the said block to hold the beading-rollers on the same in contact with the outer end of the tube or fine, substantially as shown and described.

5. In a boiler-flue beader, the combination, With a stem and a head formed thereon, of beading-rollers held in the said head and each provided with an annular semicircular bead, a block mounted to turn on the said stem and provided with radially-arranged pins or studs, beading-rollers mounted to turn on the said pins or studs, and a spindle for holding the beading-rollers in the said head in position, as set forth.

6. In a boiler-flue beader, the combination, with a stem and a head held thereon, of beading-rollers arranged in the said head and adapted to engage the inside 'of the flue o1' tube, a tapering spindle for holding the said beading-rollers in place in the said head, a block mounted to turn on the said stem and provided With radial pins or studs, and a cutter held on one of the said studs and adapted' to cut the end of the tube or due, substantially as shown and described.

'7. In a boiler-flue beader, the combination, with a stem and a head held thereon, of beading-rollers arranged in the said head and adapted to engage the inside of the 'lue or tube, a tapering spindle for holding the said beading-rollers in place in the said head, a block mounted to turn on the said stem and provided with radial pins or studs, a cutter held on one of the said studs and adapted to cut the end of the tube or flue, and a beading-roller arranged on the stud opposite the said cutter to guide the latter, substantially as shown and described.
